Table 21-7. ERRSTATn Field Descriptions (Continued)
Acknowledge error. Indicates whether an acknowledgment has been correctly received for
a transmitted message.
0 No ACK error was detected since the last read of this register.
1 An ACK error was detected since the last read of this register.
Cyclic redundancy check error. Indicates whether or not a CRC error has been detected
by the receiver.
0 No CRC error was detected since the last read of this register.
1 A CRC error was detected since the last read of this register.
Message form error.
0 No form error was detected since the last read of this register.
1 A form error was detected since the last read of this register.
Bit stuff error.
0 No bit stuffing error was detected since the last read of this register.
1 A bit stuffing error was detected since the last read of this register.
Transmit error status flag. Reflects the status of the FlexCAN transmit error counter.
0 Transmit error counter < 96
1 TXErrCounter ≥ 96
Receiver error status flag. Reflects the status of the FlexCAN receive error counter.
0 Receive error counter < 96
1 RxErrCounter ≥ 96
Idle status. Indicates when there is activity on the CAN bus.
0 The CAN bus is not idle.
1 The CAN bus is idle.
Transmit/receive status. Indicates when the FlexCAN module is transmitting or receiving a
message. TXRX has no meaning when IDLE = 1.
0 The FlexCAN is receiving a message if IDLE = 0.
1 The FlexCAN is transmitting a message if IDLE = 0.
Fault confinement state. Indicates the confinement state of the FlexCAN module, as
shown below. If the CANCTRLn[LOM] bit is set, FLTCONF will indicate error-passive.
Since the CANCTRLn register is not affected by soft reset, the FLTCONF field will not be
affected by soft reset if the LOM bit is set.
00 Error active
01 Error passive
1x Bus off
Reserved, should be cleared.
Bus off interrupt. Used to request an interrupt when the FlexCAN enters the bus off state.
The user must write a 1 to clear this bit. Writing 0 has no effect.
0 No bus off interrupt requested.
1 This bit is set when the FlexCAN state changes to bus off. If the CANCTRLn[BOFFMSK]
bit is set an interrupt request is generated. This interrupt is not requested after reset.
